DETAILED DESCRIPTION

Field crops are bred through techniques that take advantage of the plant's method of pollination. A plant is self-pollinated if pollen from one flower is transferred to the same or another flower of the same plant or a genetically identical plant. A plant is sib-pollinated when individuals within the same family or line are used for pollination. A plant is cross-pollinated if the pollen comes from a flower on a genetically different plant from a different family or line. The term “cross-pollination” used herein does not include self-pollination or sib-pollination.

The breeder often initially selects and crosses two or more parental lines, followed by repeated selfing and selection, thereby producing many unique genetic combinations. In each cycle of evaluation, the plant breeder selects the germplasm to advance to the next generation. This germplasm is grown under chosen geographical, climatic, and soil conditions, and further selections are then made. The unpredictability of genetic combinations commonly results in the expenditure of large effort to develop a new and superior canola variety.

Canola breeding programs utilize techniques such as mass and recurrent selection, backcrossing, pedigree breeding and haploidy.

Recurrent selection is used to improve populations of either self- or cross-pollinating Brassica. Through recurrent selection, a genetically variable population of heterozygous individuals is created by intercrossing several different parents. The best plants are selected based on individual superiority, outstanding progeny, and/or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued. Various recurrent selection techniques are used to improve quantitatively inherited traits controlled by numerous genes.

Breeding programs use backcross breeding to transfer genes for a simply inherited, highly heritable trait into another line that serves as the recurrent parent. The source of the trait to be transferred is called the donor parent. After the initial cross, individual plants possessing the desired trait of the donor parent are selected and are crossed (backcrossed) to the recurrent parent for several generations. The resulting plant is expected to have the attributes of the recurrent parent and the desirable trait transferred from the donor parent. This approach has been used for breeding disease resistant phenotypes of many plant species, and has been used to transfer low erucic acid and low glucosinolate content into lines and breeding populations of Brassica.

Pedigree breeding and recurrent selection breeding methods are used to develop varieties from breeding populations. Pedigree breeding starts with the crossing of two genotypes, each of which may have one or more desirable characteristics that is lacking in the other or which complements the other. If the two original parents do not provide all of the desired characteristics, other sources can be included in the breeding population. In the pedigree method, superior plants are selfed and selected in successive generations. In the succeeding generations the heterozygous condition gives way to homogeneous lines as a result of self-pollination and selection. Typically, in the pedigree method of breeding, five or more generations of selfing and selection are practiced: F₁ to F₂; F₂ to F₃; F₃ to F₄; F₄ to F₅, etc. For example, two parents that are believed to possess favorable complementary traits are crossed to produce an F₁. An F₂ population is produced by selfing one or several F₁'s or by intercrossing two F₁'s (i.e., sib mating). Selection of the best individuals may begin in the F₂ population, and beginning in the F₃ the best individuals in the best families are selected. Replicated testing of families can begin in the F₄ generation to improve the effectiveness of selection for traits with low heritability. At an advanced stage of inbreeding (i.e., F₆ and F₇), the best lines or mixtures of phenotypically similar lines commonly are tested for potential release as new cultivars. Backcrossing may be used in conjunction with pedigree breeding; for example, a combination of backcrossing and pedigree breeding with recurrent selection has been used to incorporate blackleg resistance into certain cultivars of Brassica napus.

Plants that have been self-pollinated and selected for type for many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny. If desired, double-haploid methods can also be used to extract homogeneous lines from inbred CL4787698R. A cross between two different homozygous lines produces a uniform population of hybrid plants that may be heterozygous for many gene loci. A cross of two plants each heterozygous at a number of gene loci will produce a population of hybrid plants that differ genetically and will not be uniform.

The choice of breeding or selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of cultivar used commercially, such as F₁ hybrid variety or open pollinated variety. A true breeding homozygous line can also be used as a parental line (inbred line) in a commercial hybrid. If the line is being developed as an inbred for use in a hybrid, an appropriate pollination control system should be incorporated in the line. Suitability of an inbred line in a hybrid combination will depend upon the combining ability (general combining ability or specific combining ability) of the inbred.

Various breeding procedures can be utilized with these breeding and selection methods and inbred CL4787698R. The single-seed descent procedure in the strict sense refers to planting a segregating population, harvesting a sample of one seed per plant, and using the one-seed sample to plant the next generation. When the population has been advanced from the F₂ to the desired level of inbreeding, the plants from which lines are derived will each trace to different F₂ individuals. The number of plants in a population declines each generation due to failure of some seeds to germinate or some plants to produce at least one seed. As a result, not all of the F₂ plants originally sampled in the population will be represented by a progeny when generation advance is completed.

In a multiple-seed procedure, one or more pods from each plant in a population are threshed together to form a bulk. Part of the bulk is used to plant the next generation and part is put in reserve. The procedure has been referred to as modified single-seed descent or the pod-bulk technique. It is considerably faster to thresh pods with a machine than to remove one seed from each by hand for the single-seed procedure. The multiple-seed procedure also makes it possible to plant the same number of seeds of a population each generation of inbreeding. Enough seeds are harvested to make up for those plants that did not germinate or produce seed. If desired, doubled-haploid methods can be used to extract homogeneous lines.

Molecular markers, including techniques such as Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLP), random amplified polymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP), inter-simple sequence repeats (ISSRs), sequence characterized regions (SCARs), sequence tag sites (STSs), cleaved amplified polymorphic sequences (CAPS), microsatellites, simple sequence repeats (SSRs), expressed sequence tags (ESTs), single nucleotide polymorphisms (SNPs), and diversity arrays technology (DArT), sequencing, and the like may be used in plant breeding methods using CL4787698R. One use of molecular markers is Quantitative Trait Loci (QTL) mapping. QTL mapping is the use of markers which are known to be closely linked to alleles that have measurable effects on a quantitative trait. Selection in the breeding process is based upon the accumulation of markers linked to the positive effecting alleles and/or the elimination of the markers linked to the negative effecting alleles in the plant's genome.

Molecular markers can also be used during the breeding process for the selection of qualitative traits. For example, markers closely linked to alleles or markers containing sequences within the actual alleles of interest can be used to select plants that contain the alleles of interest during a backcrossing breeding program. The markers can also be used to select for the genome of the recurrent parent and against the markers of the donor parent. Using this procedure can minimize the amount of genome from the donor parent that remains in the selected plants. It can also be used to reduce the number of crosses back to the recurrent parent needed in a backcrossing program. The use of molecular markers in the selection process is often called Genetic Marker Enhanced Selection or Marker Assisted Selection (MAS).

Methods of isolating nucleic acids from CL4787698R and methods for performing genetic marker profiles using SNP and SSR polymorphisms are provided. SNPs are genetic markers based on a polymorphism in a single nucleotide. A marker system based on SNPs can be highly informative in linkage analysis relative to other marker systems in that multiple alleles may be present.

A method comprising isolating nucleic acids, such as DNA, from a plant, a plant part, plant cell or a seed of the canola varieties disclosed herein is provided. The method can include mechanical, electrical and/or chemical disruption of the plant, plant part, plant cell or seed, contacting the disrupted plant, plant part, plant cell or seed with a buffer or solvent, to produce a solution or suspension comprising nucleic acids, optionally contacting the nucleic acids with a precipitating agent to precipitate the nucleic acids, optionally extracting the nucleic acids, and optionally separating the nucleic acids such as by centrifugation or by binding to beads or a column, with subsequent elution, or a combination thereof. If DNA is being isolated, an RNase can be included in one or more of the method steps. The nucleic acids isolated can comprise all or substantially all of the genomic DNA sequence, all or substantially all of the chromosomal DNA sequence or all or substantially all of the coding sequences (cDNA) of the plant, plant part, or plant cell from which they were isolated. The nucleic acids isolated can comprise all, substantially all, or essentially all of the genetic complement of the plant. The nucleic acids isolated can comprise a genetic complement of the canola variety. The amount and type of nucleic acids isolated may be sufficient to permit whole genome sequencing of the plant from which they were isolated or chromosomal marker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plant part, seed or cell, which nucleic acids can be, for example, analyzed to produce data. The data can be recorded. The nucleic acids from the disrupted cell, the disrupted plant, plant part, plant cell or seed or the nucleic acids following isolation or separation can be contacted with primers and nucleotide bases, and/or a polymerase to facilitate PCR sequencing or marker analysis of the nucleic acids. In some examples, the nucleic acids produced can be sequenced or contacted with markers to produce a genetic profile, a molecular profile, a marker profile, a haplotype, or any combination thereof. In some examples, the genetic profile or nucleotide sequence is recorded on a computer readable medium. In other examples, the methods may further comprise using the nucleic acids produced from plants, plant parts, plant cells or seeds in a plant breeding program, for example in making crosses, selection and/or advancement decisions in a breeding program. Crossing includes any type of plant breeding crossing method, including but not limited to crosses to produce hybrids, outcrossing, selfing, backcrossing, locus conversion, introgression and the like. Favorable genotypes and or marker profiles, optionally associated with a trait of interest, may be identified by one or more methodologies. In some examples one or more markers are used, including but not limited to restriction fragment length polymorphism (RFLP), random amplified polymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP), inter-simple sequence repeats (ISSRs), sequence characterized regions (SCARs), sequence tag sites (STSs), cleaved amplified polymorphic sequences (CAPS), microsatellites, simple sequence repeats (SSRs), expressed sequence tags (ESTs), single nucleotide polymorphisms (SNPs), and diversity arrays technology (DArT), sequencing, and the like. In some methods, a target nucleic acid is amplified prior to hybridization with a probe. In other cases, the target nucleic acid is not amplified prior to hybridization, such as methods using molecular inversion probes. In some examples, the genotype related to a specific trait is monitored, while in other examples, a genome-wide evaluation including but not limited to one or more of marker panels, library screens, association studies, microarrays, gene chips, expression studies, or sequencing such as whole-genome resequencing and genotyping-by-sequencing (GBS) may be used. In some examples, no target-specific probe is needed, for example by using sequencing technologies, including but not limited to next-generation sequencing methods (see, for example, Metzker (2010) Nat Rev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such as sequencing by synthesis (e.g., Roche 454 pyrosequencing, Illumina Genome Analyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation (e.g., SOLiD from Applied Biosystems, and Polnator system from Azco Biotech), and single molecule sequencing (SMS or third-generation sequencing) which eliminate template amplification (e.g., Helicos system, and PacBio RS system from Pacific BioSciences). Further technologies include optical sequencing systems (e.g., Starlight from Life Technologies), and nanopore sequencing (e.g., GridION from Oxford Nanopore Technologies). Each of these may be coupled with one or more enrichment strategies for organellar or nuclear genomes in order to reduce the complexity of the genome under investigation via PCR, hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoS ONE 6:e19379), and expression methods. In some examples, no reference genome sequence is needed in order to complete the analysis. CL4787698R and its plant parts can be identified through a molecular marker profile. Such plant parts may be either diploid or haploid. Also encompassed and described are plants and plant parts substantially benefiting from the use of variety CL4787698R in their development, such as variety CL4787698R comprising a locus conversion or single locus conversion.

The production of doubled haploids can also be used for the development of inbreds from CL4787698R in a breeding program. In Brassica napus, microspore culture technique is used in producing haploid embryos. The haploid embryos are then regenerated on appropriate media as haploid plantlets, doubling chromosomes of which results in doubled haploid plants. This can be advantageous because the process omits the generations of selfing needed to obtain a homozygous plant from a heterozygous source.

Controlling Self-Pollination

Canola varieties are mainly self-pollinated. A pollination control system and effective transfer of pollen from one parent to the other provides an effective method for producing hybrid canola seed and plants. For example, the ogura cytoplasmic male sterility (CMS) system, developed via protoplast fusion between radish (Raphanus sativus) and rapeseed (Brassica napus), is one of the most frequently used methods of hybrid production. It provides stable expression of the male sterility trait and an effective nuclear restorer gene. The OGU INRA restorer gene, Rf1 originating from radish has improved versions.

Brassica hybrid varieties can be developed using self-incompatible (SI), cytoplasmic male sterile (CMS) or nuclear male sterile (NMS) Brassica plants as the female parent such that only cross pollination will occur between the hybrid parents.

In one instance, production of F₁ hybrids includes crossing a CMS Brassica female parent with a pollen-producing male Brassica has a fertility restorer gene (Rf gene). The presence of an Rf gene means that the F₁ generation will not be completely or partially sterile, so that either self-pollination or cross pollination may occur. Self pollination of the F₁ generation to produce several subsequent generations verifies that a desired trait is heritable and stable and that a new variety has been isolated.

Other sources and refinements of CMS sterility in canola include the Polima cytoplasmic male sterile plant, as well as those of U.S. Pat. No. 5,789,566, DNA sequence imparting cytoplasmic male sterility, mitochondrial genome, nuclear genome, mitochondria and plant containing said sequence and process for the preparation of hybrids; See U.S. Pat. Nos. 4,658,085, 5,973,233 and 6,229,072.

Hybrid Development

For many traits the true genotypic value may be masked by other confounding plant traits or environmental factors. One method for identifying a superior plant is to observe its performance relative to other experimental plants and to one or more widely grown standard varieties. If a single observation is inconclusive, replicated observations provide a better estimate of the genetic worth.

As a result of the advances in sterility systems, lines are developed that can be used as an open pollinated variety (i.e., a pureline cultivar) and/or as a sterile inbred (female) used in the production of F₁ hybrid seed. In the latter case, favorable combining ability with a restorer (male) would be desirable.

The development of a canola hybrid generally involves three steps: (1) the selection of plants from various germplasm pools for initial breeding crosses; (2) generation of inbred lines, such as by selfing of selected plants from the breeding crosses for several generations to produce a series of different inbred lines, which breed true and are highly uniform; and (3) crossing the selected inbred lines with different inbred lines to produce the hybrids.

Combining ability of a line, as well as the performance of the line per se, is a factor in the selection of improved canola lines that may be used as inbreds. Combining ability refers to a line's contribution as a parent when crossed with other lines to form hybrids. The hybrids formed for the purpose of selecting superior lines are designated test crosses. One way of measuring combining ability is by using breeding values. Breeding values are based on the overall mean of a number of test crosses. This mean is then adjusted to remove environmental effects and it is adjusted for known genetic relationships among the lines.

Brassica napus canola plants, absent the use of sterility systems, are recognized to commonly be self-fertile with approximately 70 to 90 percent of the seed normally forming as the result of self-pollination. The percentage of cross pollination may be further enhanced when populations of recognized insect pollinators at a given growing site are greater. Thus open pollination is often used in commercial canola production.

Locus Conversions of Canola Variety CL4787698R

CL4787698R represents a new base genetic line into which a new locus or trait may be introduced. Direct transformation, genetic editing or gene modification such as described herein and backcrossing can be used to accomplish such an introgression. The term locus conversion is used to designate the product of such an introgression.

Backcrossing can be used to improve inbred varieties and a hybrid variety which is made using those inbreds. Backcrossing can be used to transfer a specific desirable trait from one variety, the donor parent, to an inbred called the recurrent parent which has overall good agronomic characteristics yet that lacks the desirable trait. This transfer of the desirable trait into an inbred with overall good agronomic characteristics can be accomplished by first crossing a recurrent parent to a donor parent (non-recurrent parent). The progeny of this cross is then mated back to the recurrent parent followed by selection in the resultant progeny for the desired trait to be transferred from the non-recurrent parent.

Traits may be used by those of ordinary skill in the art to characterize progeny. Traits are commonly evaluated at a significance level, such as a 1%, 5% or 10% significance level, when measured in plants grown in the same environmental conditions. For example, a locus conversion of CL4787698R may be characterized as having essentially the same phenotypic traits as CL4787698R or otherwise all of the physiological and morphological characteristics of CL4787698R. The traits used for comparison may be those traits shown in Table 1. Molecular markers can also be used during the breeding process for the selection of qualitative traits. For example, markers can be used to select plants that contain the alleles of interest during a backcrossing breeding program. The markers can also be used to select for the genome of the recurrent parent and against the genome of the donor parent. Using this procedure can minimize the amount of genome from the donor parent that remains in the selected plants.

A locus conversion of CL4787698R may contain at least 1, 2, 3, 4 or 5 locus conversions, and fewer than 15, 10, 9, 8, 7, or 6 locus conversions. A locus conversion of CL4787698R will otherwise retain the genetic integrity of CL4787698R. For example, a locus conversion of CL4787698R can be developed when DNA sequences are introduced through backcrossing, with a parent of CL4787698R utilized as the recurrent parent. Both naturally occurring and transgenic DNA sequences may be introduced through backcrossing techniques. A backcross conversion may produce a plant with a locus conversion in at least one or more backcrosses, including at least 2 crosses, at least 3 crosses, at least 4 crosses, at least 5 crosses and the like. Molecular marker assisted breeding or selection may be utilized to reduce the number of backcrosses necessary to achieve the backcross conversion. For example, a backcross conversion can be made in as few as two backcrosses. A locus conversion of CL4787698R can be determined through the use of a molecular profile. A locus conversion of CL4787698R may have at least 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% A of the molecular markers, or molecular profile, of CL4787698R. Examples of molecular markers that could be used to determine the molecular profile include RFLP, PCR analysis, SSR and SNPs.

Examples of locus conversions or transgenes which may be using include one or more that confer male sterility, a site for site-specific recombination, abiotic stress tolerance, altered phosphate content, altered antioxidants, altered fatty acid content, altered essential amino acid content, altered carbohydrate content, herbicide resistance, insect resistance, disease resistance or a combination thereof. Other desirable traits which may be modified include tolerance to heat and drought, reducing the time to crop maturity, greater yield, and better agronomic quality, increased amount or rate of germination, stand establishment, growth rate, maturity, and plant and pod height.

Disease—Sclerotinia

Sclerotinia infects over 100 species of plants, including Brassica species. Sclerotinia sclerotiorum is responsible for over 99% of Sclerotinia disease, while Sclerotinia minor produces less than 1% of the disease. Sclerotinia produces sclerotia, irregularly-shaped, dark overwintering bodies, which can endure in soil for four to five years. The sclerotia can germinate carpogenically or myceliogenically, depending on the environmental conditions and crop canopies. The two types of germination cause two distinct types of diseases. Sclerotia that germinate carpogenically produce apothecia and ascospores that infect above-ground tissues, resulting in stem blight, stalk rot, head rot, pod rot, white mold and blossom blight of plants. Sclerotia that germinate myceliogenically produce mycelia that infect root tissues, causing crown rot, root rot and basal stalk rot.

Sclerotinia causes Sclerotinia stem rot, also known as white mold, in Brassica, including canola. The disease is favored by moist soil conditions (at least 10 days at or near field capacity) and temperatures of 15-25° C., prior to and during canola flowering. The spores cannot infect leaves and stems directly; they must first land on flowers, fallen petals, and pollen on the stems and leaves. The fungal spores use the flower parts as a food source as they germinate and infect the plant.

The severity of Sclerotinia in Brassica is variable, and is dependent on the time of infection and climatic conditions, being favored by cool temperatures between 20 and 25° C., prolonged precipitation and relative humidities of greater than 80%. Losses ranging from 5 to 100% have been reported for individual fields. Sclerotinia can cause heavy losses in wet swaths and result in economic losses of millions of dollars.

The symptoms of Sclerotinia infection usually develop several weeks after flowering begins. The infections often develop where the leaf and the stem join. Infected stems appear bleached and tend to shred. Hard black fungal sclerotia develop within the infected stems, branches, or pods. Plants infected at flowering produce little or no seed. Plants with girdled stems wilt and ripen prematurely. Severely infected crops frequently lodge, shatter at swathing, and make swathing more time consuming. Infections can occur in all above-ground plant parts, especially in dense or lodged stands, where plant-to-plant contact facilitates the spread of infection. New sclerotia carry the disease over to the next season.

Conventional methods for control of Sclerotinia diseases include (a) chemical control (fungicides such as benomyl, vinclozolin, iprodione, azoxystrobin, prothioconazole, boscalid)., (b) disease resistance (such as partial resistance and breeding for favorable morphologies such as increased standability, reduced petal retention, branching (less compact and/or higher), and early leaf abscission) and (c) cultural control.

Methods for generating Sclerotinia resistant Brassica plants using inbred line CL4787698R are provided, including crossing with one or more lines containing one or more genes contributing to Sclerotinia resistance and selecting for resistance. In some embodiments, CL4787698R can be modified to have resistance to Sclerotinia.

The inbred line CL4787698R can be used in breeding techniques to create canola hybrids. For example, inbred line CL4787698R may be used as a female parent, male parent or restorer (R-line), A-line, maintainer (B-line) in a canola hybrid.

An OGU restorer version, or R-line, of variety CL4787698R is provided which is a male line that carries a gene for the restoration of fertility. When a sterile CMS version of an inbred is pollinated by a male line that carries a gene for the restoration of fertility, it results in a fertile hybrid. Generally, the seed produced from this cross is the seed that is commercially sold.

There are a number of analytical methods available to determine the phenotypic stability of a canola variety. Phenotypic trait data are usually collected in field experiments including for example traits associated with seed yield, seed oil content, seed protein content, fatty acid composition of oil, glucosinolate content of meal, growth habit, lodging resistance, plant height, shattering resistance, etc.

In addition to phenotypic observations, the genotype of a plant can also be examined. A plant's genotype can be used to identify plants of the same variety or a related variety, or pedigree. Genotyping techniques include Isozyme Electrophoresis, RFLPs, RAPDs, AP-PCR, DAF, SCARs, AFLPs, SSRs which are also referred to as Microsatellites and SNPs.

The variety described herein has shown uniformity and stability for all traits, such as described in Table 1. When preparing the detailed phenotypic information, plants of variety CL4787698R were observed while being grown using conventional agronomic practices.

Variety CL4787698R can be advantageously used in accordance with the breeding methods described herein and those known in the art to produce hybrids and other progeny plants retaining desired trait combinations of CL4787698R. Provided are methods for producing a canola plant by crossing a first parent canola plant with a second parent canola plant wherein either the first or second parent canola plant is canola variety CL4787698R. Further, both first and second parent canola plants can come from the canola variety CL4787698R. Either the first or the second parent plant may be male sterile.

Still further, methods to produce a CL4787698R-derived canola plant are provided by crossing canola variety CL4787698R with a second canola plant and growing the progeny seed, and repeating the crossing and growing steps with the canola CL4787698R-derived plant at least 1, 2 or 3 times and less than 7, 6, 5, 4, 3 or 2 times. Any such methods using the canola variety CL4787698R may include one or more of open pollination, selfing, backcrosses, hybrid production, crosses to populations, and the like. All plants produced using canola variety CL4787698R as a parent, including plants derived from canola variety CL4787698R are provided herein. Plants derived or produced from CL4787698R may include components for either male sterility or for restoration of fertility. Advantageously, the canola variety is used in crosses with other, different, canola plants to produce first generation (F₁) canola hybrid seeds and plants with superior characteristics.

A single-gene or a single locus conversion of CL4787698R is provided. Single-gene conversions and single locus conversions can occur when DNA sequences are introduced through traditional (non-transformation) breeding techniques, such as backcrossing. DNA sequences, whether naturally occurring, modified or transgenes, may be introduced using these traditional breeding techniques. Desired traits transferred through this process include, but are not limited to, fertility restoration, fatty acid profile modification, oil content modification, protein quality or quantity modification, other nutritional enhancements, industrial enhancements, disease resistance, insect resistance, herbicide resistance and yield enhancements. The trait of interest is transferred from the donor parent to the recurrent parent, in this case, the canola plant disclosed herein. Single-gene traits may result from the transfer of either a dominant allele or a recessive allele. Selection of progeny containing the trait of interest is done by direct selection for a trait associated with a dominant allele. Selection of progeny for a trait that is transferred via a recessive allele will require growing and selfing the first backcross to determine which plants carry the recessive alleles. Recessive traits may require additional progeny testing in successive backcross generations to determine the presence of the gene of interest.

It should be understood that the canola variety described herein can, through routine manipulation by cytoplasmic genes, nuclear genes, or other factors, be produced in a male-sterile or restorer form as described in the references discussed earlier. Canola variety CL4787698R can be manipulated to be male sterile by any of a number of methods known in the art, including by the use of mechanical methods, chemical methods, SI, CMS (either ogura or another system) or NMS. The term “manipulated to be male sterile” refers to the use of any available techniques to produce a male sterile version of canola variety CL4787698R. The male sterility may be either partial or complete male sterility. F1 hybrid seed and plants produced by the use of canola variety CL4787698R are provided. Canola variety CL4787698R can also further comprise a component for fertility restoration of a male sterile plant, such as an Rf restorer gene. In this case, canola variety CL4787698R could then be used as the male plant in hybrid seed production.

CL4787698R can be used in tissue culture. As used herein, the term plant includes plant protoplasts, plant cell tissue cultures from which canola plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of plants, such as embryos, pollen, ovules, seeds, flowers, leaves, husks, stalks, roots, root tips, anthers and the like. Tissue culture and microspore cultures and the regeneration of canola plants therefrom are provided.

The utility of canola variety CL4787698R also extends to crosses with other species than just Brassica napus. Commonly, suitable species will be of the family Brassicae.

Molecular biological techniques allow the isolation and characterization of genetic elements with specific functions, such as encoding specific protein products. The genome of plants can be engineered to contain and express foreign genetic elements, or additional or modified versions of native or endogenous genetic elements in order to alter the traits of a plant in a specific manner. Any DNA sequences, whether from a different species or from the same species, that are inserted into the genome using transformation are referred to herein collectively as “transgenes”. Gene editing can insert, delete or substitute native polynucleotide sequences to produce increased or decreased expression or activity of a polypeptide of interest. Described herein are transformed and edited versions of the claimed canola variety CL4787698R.

Numerous methods for plant transformation have been developed, including biological and physical plant transformation protocols. In addition, expression vectors and in vitro culture methods for plant cell or tissue transformation and regeneration of plants are available. The most prevalent types of plant transformation involve the construction of an expression vector. Such a vector comprises a DNA sequence that contains a gene under the control of or operatively linked to a regulatory element, for example a promoter. The vector may contain one or more genes and one or more regulatory elements.

In general, methods to transform, modify, edit or alter plant endogenous genomic DNA include altering the plant native DNA sequence or introducing a pre-existing transgenic sequence including regulatory elements, coding and non-coding sequences. Genetic transformation methods include introduction of foreign or heterologous sequences and genome editing techniques which modify the native sequence. Transformation methods can be used, for example, to target nucleic acids to pre-engineered target recognition sequences in the genome. Such pre-engineered target sequences may be introduced by genome editing or modification. As an example, a genetically modified plant variety is generated using “custom” or engineered endonucleases such as meganucleases produced to modify plant genomes (see e.g., WO 2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Another site-directed engineering method is through the use of zinc finger domain recognition coupled with the restriction properties of restriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet. 11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. A transcription activator-like (TAL) effector-DNA modifying enzyme (TALE or TALEN) is also used to engineer changes in plant genome. See e.g., US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Boch et al., (2009), Science 326(5959): 1509-12. Site-specific modification of plant genomes can also be performed using the bacterial type II CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated) system. See e.g., Belhaj et al., (2013), Plant Methods 9: 39; The Cas9/guide RNA-based system allows targeted cleavage of genomic DNA guided by a customizable small noncoding RNA in plants (see e.g., WO 2015026883A1).

A genetic trait which has been engineered into a particular canola plant using transformation and/or gene editing techniques, could be moved into another line using traditional breeding techniques that are well known in the plant breeding arts. For example, a backcrossing approach could be used to move a transgene or modified gene from a transformed or modified canola plant to an elite inbred line and the resulting progeny would comprise a transgene or modified gene. Also, if an inbred line was used for the transformation or genetic modification then the transgenic or modified plants could be crossed to a different line in order to produce a transgenic or modified hybrid canola plant. As used herein, “crossing” can refer to a simple X by Y cross, or the process of backcrossing, depending on the context. Various genetic elements can be introduced into the plant genome using transformation or gene editing. These elements include but are not limited to genes; coding sequences; inducible, constitutive, and tissue specific promoters; enhancing sequences; and signal and targeting sequences.

Transgenic and modified plants described herein can produce a foreign or modified protein in commercial quantities. Thus, techniques for the selection and propagation of transformed plants, which are well understood in the art, may yield a plurality of transgenic or modified plants which are harvested in a conventional manner, and a foreign or modified protein then can be extracted from a tissue of interest or from total biomass.

A genetic map can be generated, for example via conventional RFLP, PCR analysis, SSR and SNPs, which identifies the approximate chromosomal location of the integrated DNA molecule coding for the foreign protein. Genetic or physical map information concerning chromosomal location is useful for proprietary protection of a subject transgenic or modified plant. If unauthorized propagation is undertaken and crosses made with other germplasm, the map of the integration or modified region can be compared to similar maps for suspect plants, to determine if the latter have a common parentage with the subject plant. Map comparisons would involve hybridizations, RFLP, PCR, SSR, SNP, and sequencing, all of which are conventional techniques.

Likewise, disclosed are plants genetically engineered or modified to express various phenotypes of agronomic interest. Exemplary transgenes or modified genes implicated in this regard include, but are not limited to, those categorized below.

-   1. Genes that confer resistance to pests or disease and that encode:

(A) Plant disease resistance genes. Plant defenses are often activated by specific interaction between the product of a disease resistance gene (R) in the plant and the product of a corresponding avirulence (Avr) gene in the pathogen. A plant variety can be transformed with cloned resistance gene to engineer plants that are resistant to specific pathogen strains. A plant resistant to a disease is one that is more resistant to a pathogen as compared to the wild type plant.

(B) A gene conferring resistance to fungal pathogens.

(C) A Bacillus thuringiensis protein, a derivative thereof or a synthetic polypeptide modeled thereon. DNA molecules encoding delta-endotoxin genes can be purchased from American Type Culture Collection (Manassas, Va.), for example, under ATCC Accession Nos. 40098, 67136, 31995 and 31998. Other examples of Bacillus thuringiensis transgenes are given in the following US and international patents and applications: U.S. Pat.

(F) An enzyme responsible for a hyperaccumulation of a monterpene, a sesquiterpene, a steroid, hydroxamic acid, a phenylpropanoid derivative or another non-protein molecule with insecticidal activity.

(G) An enzyme involved in the modification, including the post-translational modification, of a biologically active molecule; for example, a glycolytic enzyme, a is proteolytic enzyme, a lipolytic enzyme, a nuclease, a cyclase, a transaminase, an esterase, a hydrolase, a phosphatase, a kinase, a phosphorylase, a polymerase, an elastase, a chitinase and a glucanase, whether natural or synthetic. See PCT Application No. WO 93/02197, which discloses the nucleotide sequence of a callase gene. DNA molecules which contain chitinase-encoding sequences can be obtained, for example, from the ATCC under Accession Nos. 39637 and 67152. See also U.S. Pat. No. 6,563,020.

(H) A molecule that stimulates signal transduction. For example, nucleotide sequences encoding calmodulin.

(I) A hydrophobic moment peptide. See, U.S. Pat. Nos. 5,580,852 and 5,607,914.

(J) A membrane permease, a channel former or a channel blocker. For example, a cecropin-beta lytic peptide analog.

(K) A viral-invasive protein or a complex toxin derived therefrom. For example, the accumulation of viral coat proteins in transformed plant cells imparts resistance to viral infection and/or disease development effected by the virus from which the coat protein gene is derived, as well as by related viruses. Coat protein-mediated resistance has been conferred upon transformed plants against alfalfa mosaic virus, cucumber mosaic virus, tobacco streak virus, potato virus X, potato virus Y, tobacco etch virus, tobacco rattle virus and tobacco mosaic virus.

(L) An insect-specific antibody or an immunotoxin derived therefrom. Thus, an antibody targeted to a critical metabolic function in the insect gut would inactivate an affected enzyme, killing the insect.

(M) A virus-specific antibody. For example, transgenic plants expressing recombinant antibody genes can be protected from virus attack.

(N) A developmental-arrestive protein produced in nature by a pathogen or a parasite; for example, fungal endo alpha-1,4-D-polygalacturonases.

Nos. 6,566,587; 6,338,961; 6,248,876; 6,040,497; 5,804,425; 5,633,435; 5,145,783; 4,971,908; 5,312,910; 5,188,642; 4,940,835; 5,866,775; 6,225,114; 6,130,366; 5,310,667; 4,535,060; 4,769,061; 5,633,448; 5,510,471; Re. 36,449; RE 37,287 E; and 5,491,288; and international publications EP1173580; WO 01/66704; EP1173581 and EP1173582. A DNA molecule encoding a mutant aroA gene can be obtained under ATCC Accession No. 39256, see U.S. Pat. No. 4,769,061. European Patent Application No. 0 333 033, and U.S. Pat. No. 4,975,374 disclose nucleotide sequences of glutamine synthetase genes which confer resistance to herbicides such as L-phosphinothricin. The nucleotide sequence of a phosphinothricin-acetyl-transferase gene is provided in European Application No. 0 242 246. See also, U.S. Pat. Nos. 5,969,213; 5,489,520; 5,550,318; 5,874,265; 5,919,675; 5,561,236; 5,648,477; 5,646,024; 6,177,616 and 5,879,903.

Other genes that confer tolerance to herbicides include: a gene encoding a chimeric protein of rat cytochrome P4507A1 and yeast NADPH-cytochrome P450 oxidoreductase, genes for glutathione reductase and superoxide dismutase, and genes for various phosphotransferases.

(E) Protoporphyrinogen oxidase (protox) is necessary for the production of chlorophyll, which is necessary for all plant survival. The protox enzyme serves as the target for a variety of herbicidal compounds. These herbicides also inhibit growth of all the different species of plants present, causing their total destruction. The development of plants containing altered protox activity which are resistant to these herbicides are described in U.S. Pat. Nos. 6,288,306; 6,282,837; and 5,767,373; and international publication WO 01/12825.

-   3. Transgenes that confer or contribute to an altered grain     characteristic, such as:

(A) Altered fatty acids, for example, by

-   -   (1) Down-regulation of stearoyl-ACP desaturase to increase         stearic acid content of the plant. See, WO99/64579,     -   (2) Elevating oleic acid via FAD-2 gene modification and/or         decreasing linolenic acid via FAD-3 gene modification, See, U.S.         Pat. Nos. 6,063,947; 6,323,392; 6,372,965 and WO 93/11245,     -   (3) Altering conjugated linolenic or linoleic acid content, such         as in WO 01/12800,     -   (4) Altering LEC1, AGP, Dek1, Superalt mi1ps, various Ipa genes         such as Ipa1, Ipa3, hpt or hggt.

(B) Altered phosphorus content, for example, by the

-   -   (1) Introduction of a phytase-encoding gene would enhance         breakdown of phytate, adding more free phosphate to the         transformed plant, such as for example, using an Aspergillus         niger phytase gene.     -   (2) Up-regulation of a gene that reduces phytate content.

-   4. Genes that control pollination, hybrid seed production or     male-sterility:

There are several methods of conferring genetic male sterility available, such as multiple mutant genes at separate locations within the genome that confer male sterility, as disclosed in U.S. Pat. Nos. 4,654,465 and 4,727,219 and chromosomal translocations, see U.S. Pat. Nos. 3,861,709 and 3,710,511. U.S. Pat. No. 5,432,068 describes a system of nuclear male sterility which includes replacing the native promoter of an essential male fertility gene with an inducible promoter to create a male sterile plant that can have fertility restored by inducing or turning “on”, the promoter such that the male fertility gene is transcribed.

(A) Introduction of a deacetylase gene under the control of a tapetum-specific promoter and with the application of the chemical N-Ac-PPT (WO 01/29237).

(B) Introduction of various stamen-specific promoters (WO 92/13956, WO 92/13957).

(C) Introduction of the barnase and the barstar gene.

For additional examples of nuclear male and female sterility systems and genes, see also, U.S. Pat. Nos. 5,859,341; 6,297,426; 5,478,369; 5,824,524; 5,850,014 and 6,265,640.

Also see, U.S. Pat. No. 5,426,041 (relating to a method for the preparation of a seed of a plant comprising crossing a male sterile plant and a second plant which is male fertile), U.S. Pat. No. 6,013,859 (molecular methods of hybrid seed production) and U.S. Pat. No. 6,037,523 (use of male tissue-preferred regulatory region in mediating fertility).

-   5. Genes that create a site for site specific DNA integration.

This includes the introduction of FRT sites that may be used in the FLP/FRT system and/or Lox sites that may be used in the Cre/Loxp system. Other systems that may be used include the Gin recombinase of phage Mu, the Pin recombinase of E. coli, and the R/RS system of the pSR1 plasmid.

-   6. Genes that affect abiotic stress resistance (including but not     limited to flowering and seed development, enhancement of nitrogen     utilization efficiency, altered nitrogen responsiveness, drought     resistance or tolerance, cold resistance or tolerance, and salt     resistance or tolerance) and increased yield under stress.

For example, see, U.S. Pat. Nos. 5,892,009, 5,965,705, 5,929,305, 5,891,859, 6,417,428, 6,664,446, 6,706,866, 6,717,034, 6,801,104. CBF genes and transcription factors effective in mitigating the negative effects of freezing, high salinity, and drought on plants can be used. Altering abscisic acid in plants may result in increased yield and/or increased tolerance to abiotic stress. Modifying cytokinin expression may result in plants with increased drought tolerance, and/or increased yield. Enhancement of nitrogen utilization and altered nitrogen responsiveness can be carried out. Ethylene alteration, plant transcription factors or transcriptional regulators of abiotic stress may be used. Other genes and transcription factors that affect plant growth and agronomic traits such as yield, flowering, plant growth and/or plant structure, can be introduced or introgressed into plants.

INDUSTRIAL APPLICABILITY

The seed of the CL4787698R variety or grain produced on its hybrids, plants produced from such seed, and various parts of the CL4787698R variety canola plant or its progeny can be utilized in the production of an edible vegetable oil, meal, other food products or silage for animal feed in accordance with known techniques. The oil as removed from the seeds can be used in food applications such as a salad or frying oil. Canola oil has low levels of saturated fatty acids. “Canola” refers to rapeseed (Brassica) which (1) has an erucic acid (C_(22:1)) content of at most 2% (preferably at most 0.5% or 0%) by weight based on the total fatty acid content of a seed, and (2) produces, after crushing, an air-dried meal containing less than 30 μmol glucosinolates per gram of defatted (oil-free) meal. The oil also finds utility in industrial applications. The solid meal component derived from seeds after oil extraction can be used as a nutritious livestock feed. Examples of canola grain as a commodity plant product include, but are not limited to, oils and fats, meals and protein, and carbohydrates. Methods of processing seeds and grain of CL4787698R or of a hybrid and grain produced on the hybrid to produce commodity products such as oil and protein meal are provided.
